Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F4301X is determined by strict equivalence across the following parameters:

• Resistance value: 4.3 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur feature presence
• RoHS3 compliance
• MSL rating: 1

The ERJ-U02F4301X meets all these criteria and qualifies as a direct substitute. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F4301X and ERJ-U02F4301X are active production components manufactured by Panasonic Electronic Components. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. The ERJ-U02F4301X currently maintains higher inventory levels (13,341 units) compared to the ERJ-S02F4301X (807 units). Both parts carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, making them functionally interchangeable in applications requiring 4.3 kOhms ±1% thick film resistors in 0402 package format with automotive-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F4301X replace ERJ-S02F4301X in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications, mechanical dimensions, and operating temperature ranges. They are functionally equivalent for automotive circuit applications.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERJ-S02F4301X and ERJ-U02F4301X are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification with MSL rating of 1 (unlimited moisture sensitivity).

Q: What is the difference between the ERJ-S02 and ERJ-U02 series designations?

A: The series designation difference does not affect electrical or mechanical performance. Both series share identical specifications for this 4.3 kOhms ±1% 0402 resistor configuration.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -55°C to 155°C with a temperature coefficient of ±200ppm/°C, meeting automotive environmental requirements.
